Description

Technical Field

[0001] This invention relates to the field of water channel technology, and more specifically, to a cold-region corrosion-resistant prefabricated metal water channel and its assembly method. Background Technology

[0002] Farmland irrigation often utilizes river water, which is introduced into the farmland through "ditches" dug in the ground. Water canals are artificially excavated waterways, which are divided into main canals and branch canals. Main canals and branch canals are generally constructed with stone or cement. In cold-region construction, water canals are also needed to assist in the water diversion operation in cold regions.

[0003] In the prior art, a rapid construction method for prefabricated cast-in-place hybrid water conveyance canals, with publication number CN119980963A, includes the following steps: S01, excavating the slope of the canal, the width of the slope being greater than the width of the canal; S02, prefabricating a prefabricated bottom canal, the prefabricated bottom canal including a bottom slab, with inclined webs on both sides, the height of the webs being higher than the height of the water accumulation in the original canal; S03, laying a bedding layer at the bottom of the excavated canal; S04, hoisting the prefabricated bottom canal; S05, assembling each segment... The prefabricated bottom channel is hoisted and tensioned in sections continuously; S06, after the prefabricated bottom channel is constructed, the side panels are constructed; S07, after the channel is constructed, backfill is applied to the outside of the channel, and the backfill soil is placed between the outside of the channel and the slope and compacted; the above steps complete the rapid construction of the channel. By adopting the construction method of prefabricated bottom channel and cast-in-place side panels, construction can be carried out in water, and the rainy season will not affect the construction period, while the side panels can be constructed in a dry state, achieving a balance between construction efficiency and cost.

[0004] However, while the aforementioned canal construction device can assist in the installation of canal formwork, its effectiveness in assembling and interlocking formwork is poor. Furthermore, its auxiliary support for the main formwork during pre-installation is inadequate, reducing its stability during construction. Additionally, when used in cold environments for extended periods, the canal formwork is ineffective at preventing icing at the water-contact points, and its ability to pre-break up ice is also poor, failing to meet user needs. Therefore, we propose a cold-weather corrosion-resistant prefabricated metal canal and its assembly method. Summary of the Invention

[0005] To address the problems mentioned in the background, this invention provides a cold-weather corrosion-resistant prefabricated metal water channel and its assembly method, which solves the problems mentioned in the background art, such as poor interlocking assembly between templates, reduced support stability of the main template during construction, poor anti-icing effect of water channel templates at the water-water contact points when used for a long time in cold environments, and poor pre-breaking effect of ice blocks in the event of icing.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows: A cold-region corrosion-resistant prefabricated metal water channel includes a main template, side templates detachably connected to the side walls of the main template, a first insertion hole on the outer wall of the main template, a first bolt penetrating the outer wall of the side template inserted into the inner wall of the first insertion hole, a first nut threadedly connected to the outer wall of the first bolt and fitting against the surface of the side template, a second insertion hole at the connection between the outer wall of the side template and the first bolt, a second bolt penetrating the top of the side template inserted into the outer wall of the main template, a first connection hole at the connection between the top of the side template and the second bolt, and a second connection hole at the connection between the outer wall of the main template and the second bolt. The outer wall of the main template is detachably connected to an installation block, the outer wall of the installation block is rotatably connected to a connecting block, the outer wall of the connecting block is fixedly connected to a connecting frame, the inner side wall of the connecting frame is rotatably connected to a connecting gear, the rotation center of the connecting gear is fixedly connected to a support rod via a rotating shaft, the inner wall of the support rod is slidably connected to an adjusting rod, one end of the adjusting rod is rotatably connected to a flipping block, and the outer wall of the flipping block is threadedly connected to an anchor rod. The outer wall of the main template is slidably connected to a threaded slide rod, and the outer wall of the threaded slide rod is fixedly connected to a main striking rod. The side wall of the main striking rod is telescopically connected to a secondary striking rod. When laying metal water channels in cold regions for water diversion, in order to improve the efficiency of water channel construction in cold regions and the stability of the assembly and use of water channel templates, the movement of support rods and anchor rods allows the support rods to adjust and support both sides of the main template. Through the docking of holes, the side templates are spliced ​​with the main template, improving the effect of rapid construction and installation of multiple water channel templates.

[0007] Preferably, the surface of the main template has flow holes, and the outer wall contour of the side template is wavy.

[0008] Preferably, the outer wall of the mounting block is inserted with a third bolt that penetrates the outer wall of the main template, and the connection between the outer wall of the main template and the third bolt is provided with a mounting hole. The outer wall of the third bolt is threaded with a second nut that fits against the bottom of the main template.

[0009] Preferably, a sliding rod is slidably connected to the outer wall of the connecting frame, and a spring is sleeved on the outer wall of the sliding rod and fixedly connected to the outer wall of the connecting frame. One end of the spring is fixedly connected to a pull block fixedly connected to one end of the sliding rod, and one end of the sliding rod is fixedly connected to a locking rod that engages with the outer wall of the connecting gear. When the main template is installed and supported by the support rod, the support rod can be rotated, which will drive the connecting gear to rotate synchronously. Under the action of the inclined plane of the pressing part between the connecting gear and the locking rod, the sliding rod and the spring will be lifted until the support rod stops rotating, thereby improving the locking and fixing effect of the angle after the support rod rotates.

[0010] Preferably, the outer wall of the chuck and the outer wall of the pressing part of the connecting gear are inclined.

[0011] Preferably, a second servo motor is provided on the outer wall of the main template. The output end of the second servo motor is fixedly connected to a first threaded rod that is rotatably connected to the outer wall of the main template. A fixing groove is provided at the connection between the outer wall of the main template and the threaded sliding rod. When using the water channel to assist in the diversion of cold land water, in order to reduce the occurrence of ice in the water channel, the first servo motor is turned on and the rotation of the first threaded rod drives the main striking rod to slide along the inner wall of the fixing groove to achieve the effect of relatively loosening the inner wall of the water channel by striking.

[0012] Preferably, there are two sets of the first threaded rods, and the two sets of the first threaded rods rotate in opposite directions. The threaded slide bar and the first threaded rod are connected by a thread.

[0013] Preferably, the outer wall of the main striking rod is provided with a first servo motor. The output end of the first servo motor is fixedly connected to a second threaded rod that is rotatably connected to the outer wall of the main striking rod. The outer wall of the second threaded rod is threadedly connected to a fixed rod that is slidably connected to the outer wall of the main striking rod. A limit groove is provided at the connection between the outer wall of the main striking rod and the fixed rod. The outer wall of the fixed rod is rotatably connected to a rotating rod that is rotatably connected to the outer wall of the auxiliary striking rod. The outer wall of the auxiliary striking rod is fixedly connected to a telescopic rod that is fixedly connected to the outer wall of the main striking rod. According to the range of ice loosening on the inner wall of the water channel, the second servo motor is turned on, and the rotation of the second threaded rod drives the fixed rod to slide along the inner wall of the limit groove. Through the rotation of the rotating rod, the auxiliary striking rod that is fixedly connected to the telescopic rod slides relative to it, so as to achieve the effect of convenient adjustment of the striking range.

[0014] Preferably, there are two sets of rotating rods, and the positions of the two sets of rotating rods are symmetrical about the central axis of the fixed rod. The rotating rods and the auxiliary striking rods are arranged in a one-to-one correspondence.

[0015] The assembly method for cold-region corrosion-resistant prefabricated metal water channels includes the following steps: Step S1: Place the main template at the end of the water channel installation, and install the installation block to the main template using the third bolt. Adjust the support position of the adjusting rod and the flipping block, and support and fix the main template under the action of the anchor rod. Step S2: Fit the side templates to the main template respectively, and make the first and second insertion holes relative to each other. Insert the first bolt into the first and second insertion holes, and use the first nut to snap the side templates to the sides of the main template. Step S3: After the side template and the side of the main template are snapped together, the first connecting hole and the second connecting hole are fitted together and the second bolt is inserted. With the threaded connection of the nut, the top of the side template is snapped together with the top of the main template. Step S4: After the metal water channel is installed and put into use, in order to reduce the possibility of ice forming on the surface of the water channel plate during long periods of cold weather, the first threaded rod is periodically driven to drive the threaded slide rod to slide along the inner wall of the fixed groove, so that the main striking rod reciprocates to strike the opposite side template surface. At the same time, the rotating rod is driven to adjust the distance between the auxiliary striking rod and the main striking rod.

[0016] Compared with the prior art, the beneficial effects of this invention are as follows: (1) When laying metal water channels in cold land for water diversion, in order to improve the efficiency of water channel construction in cold land, the stability of water channel templates is achieved by using the first and second bolts, and the support rods and anchor rods are moved to adjust the support on both sides of the main template. The side templates are spliced ​​with the main templates by connecting the holes, thereby improving the effect of rapid construction and installation of multiple water channel templates.

[0017] (2) The clamp provided in this invention can rotate the support rod and drive the connecting gear to rotate synchronously when the main template is installed and supported by the support rod. Under the action of the inclined plane between the connecting gear and the clamping part, the sliding rod and the spring are lifted until the support rod stops rotating, thereby improving the clamping and fixing effect of the angle after the support rod rotates.

[0018] (3) When using the water channel to assist in the diversion of cold land, in order to reduce the occurrence of ice formation in the water channel, the first servo motor is turned on and the first threaded rod is rotated to drive the main slapping rod to slide along the inner wall of the fixed groove, thereby achieving the effect of relatively slapping and loosening the inner wall of the water channel.

[0019] (4) Based on the range of ice loosening on the inner wall of the water channel, turn on the second servo motor and drive the fixed rod to slide along the inner wall of the limiting groove through the rotation of the second threaded rod. Through the rotation connection of the rotating rod, drive the auxiliary slapping rod fixedly connected to the telescopic rod to slide relative to each other, so as to achieve the effect of convenient adjustment of the slapping range.

[0022] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below. Example

[0023] Please see Figures 1 to 9This embodiment provides a cold-region corrosion-resistant prefabricated metal water channel and its assembly method, including a main template 1, a side template 2 detachably connected to the side wall of the main template 1, a first insertion hole 3 opened on the outer wall of the main template 1, a first bolt 5 inserted through the outer wall of the side template 2 inserted into the inner wall of the first insertion hole 3, a first nut 6 threadedly connected to the outer wall of the first bolt 5 and fitting against the surface of the side template 2, a second insertion hole 7 opened at the connection between the outer wall of the side template 2 and the first bolt 5, a second bolt 10 inserted through the top of the side template 2 inserted into the outer wall of the main template 1, a first connection hole 8 opened at the connection between the top of the side template 2 and the second bolt 10, and a second connection hole 9 opened at the connection between the outer wall of the main template 1 and the second bolt 10. The outer wall of the main template 1 is detachably connected to an installation block 11. The outer wall of the installation block 11 is rotatably connected to a connecting block 15. The outer wall of the connecting block 15 is fixedly connected to a connecting frame 16. The inner side wall of the connecting frame 16 is rotatably connected to a connecting gear 17. The rotation center of the connecting gear 17 is fixedly connected to a support rod 18 via a rotating shaft. The inner wall of the support rod 18 is slidably connected to an adjusting rod 34. One end of the adjusting rod 34 is rotatably connected to a flipping block 35. The outer wall of the flipping block 35 is threadedly connected to an anchor rod 36. The outer wall of the main template 1 is slidably connected with a threaded slide rod 24, and the outer wall of the threaded slide rod 24 is fixedly connected with a main striking rod 26. The side wall of the main striking rod 26 is telescopically connected with a secondary striking rod 32. When laying metal water channels in cold land for water diversion, in order to improve the efficiency of water channel construction in cold land and improve the stability of the assembly and use of water channel templates, the movement of the support rod 18 and the anchor rod 36 allows the support rod 18 to adjust and support both sides of the main template 1, and the side template 2 is spliced ​​with the main template 1 through the docking of the holes, thereby improving the effect of rapid construction and installation of multiple water channel templates.

[0024] like Figure 2 and Figure 3 As shown, the surface of the main template 1 is provided with flow holes 4, and the outer wall contour of the side template 2 is wavy, which is conducive to the convenient dredging and flow of water through the flow holes 4.

[0025] like Figure 5As shown, a third bolt 12 is inserted into the outer wall of the mounting block 11, penetrating the outer wall of the main template 1. A mounting hole 13 is provided at the connection between the outer wall of the main template 1 and the third bolt 12. A second nut 14 is threadedly connected to the outer wall of the third bolt 12 and fits against the bottom of the main template 1. This facilitates the installation and use of the mounting block 11 by setting the third bolt 12, and enables the support rod 18 to easily adjust and support the main template 1. When the main template 1 is installed and supported by the support rod 18, the support rod 18 can be rotated, which drives the connecting gear 17 to rotate synchronously. Under the action of the inclined surface of the pressing part between the connecting gear 17 and the clamping rod 22, the sliding rod 19 and the spring 20 are lifted until the support rod 18 stops rotating, thereby improving the locking and fixing effect of the angle after the support rod 18 rotates.

[0026] like Figure 9 As shown, a sliding rod 19 is slidably connected to the outer wall of the connecting frame 16. A spring 20 is sleeved on the outer wall of the sliding rod 19 and fixedly connected to the outer wall of the connecting frame 16. A pull block 21 is fixedly connected to one end of the spring 20 and fixedly connected to one end of the sliding rod 19. A locking rod 22 is fixedly connected to one end of the sliding rod 19 and engages with the outer wall of the connecting gear 17. The locking rod 22 helps to improve the engagement and fixation effect of the connecting gear 17 after rotation.

[0027] like Figure 9 As shown, the outer wall of the locking rod 22 and the outer wall of the pressing part of the connecting gear 17 are inclined, which is beneficial to improve the locking and fixing effect of the connecting gear 17 after rotation by setting the outer wall of the locking rod 22 and the outer wall of the pressing part of the connecting gear 17 to be inclined.

[0028] like Figure 6 As shown, a second servo motor 37 is provided on the outer wall of the main template 1. The output end of the second servo motor 37 is fixedly connected to a first threaded rod 23 that is rotatably connected to the outer wall of the main template 1. A fixing groove 25 is provided at the connection between the outer wall of the main template 1 and the threaded slide rod 24. This is beneficial to achieve the effect of conveniently limiting the relative sliding of the threaded slide rod 24 through the setting of the fixing groove 25.

[0029] like Figure 8As shown, a first servo motor 27 is provided on the outer wall of the main striking rod 26. A second threaded rod 28, rotatably connected to the output end of the first servo motor 27, is fixedly connected to the outer wall of the main striking rod 26. A fixed rod 29, slidably connected to the outer wall of the main striking rod 26, is threadedly connected to the outer wall of the second threaded rod 28. A limit groove 30 is provided at the connection between the outer wall of the main striking rod 26 and the fixed rod 29. A rotating rod 31, rotatably connected to the outer wall of the auxiliary striking rod 32, is rotatably connected to the outer wall of the fixed rod 29. The telescopic rod 33 is fixedly connected to the outer wall of the main striking rod 26. This facilitates the relative telescopic movement of the auxiliary striking rod 32 by rotating the rod 31. Depending on the extent of ice loosening on the inner wall of the water channel, the second servo motor 37 is turned on, and the rotation of the second threaded rod 28 drives the fixed rod 29 to slide along the inner wall of the limiting groove 30. Through the rotation of the rotating rod 31, the auxiliary striking rod 32, which is fixedly connected to the telescopic rod 33, slides relative to the main striking rod 26, thus achieving convenient adjustment of the striking range.

[0030] like Figure 8 As shown, there are two sets of rotating rods 31. The positions of the two sets of rotating rods 31 are symmetrical about the central axis of the fixed rod 29. The rotating rods 31 and the auxiliary striking rods 32 are arranged in a one-to-one correspondence. This is beneficial to achieve the effect of telescopic movement of the auxiliary striking rods 32 by setting two sets of rotating rods 31 with their positions symmetrical about the central axis of the fixed rod 29.

[0031] The assembly method for cold-region corrosion-resistant prefabricated metal water channels includes the following steps: Step S1: Place the main template 1 at the end of the water channel installation, and install the installation block 11 to the main template 1 with the third bolt 12. Adjust the support position of the adjusting rod 34 and the flipping block 35, and support and fix the main template 1 under the action of the anchor rod 36. Step S2: Fit the side template 2 to the main template 1 respectively, and make the first insertion hole 3 and the second insertion hole 7 relative to each other. Insert the first bolt 5 into the first insertion hole 3 and the second insertion hole 7, and use the first nut 6 to snap the side template 2 to the side of the main template 1. Step S3: After the side template 2 is snapped into the side of the main template 1, the first connecting hole 8 and the second connecting hole 9 are fitted together and the second bolt 10 is inserted. With the threaded connection of the nut, the top of the side template 2 is snapped into the top of the main template 1. Step S4: After the metal water channel is installed and put into use, in order to reduce the possibility of ice forming on the surface of the water channel plate during long periods of cold weather, the first threaded rod 23 is periodically driven to drive the threaded slide rod 24 to slide along the inner wall of the fixed groove 25, so that the main striking rod 26 reciprocates to strike the surface of the opposite template 2. At the same time, the rotating rod 31 is driven to adjust the distance between the auxiliary striking rod 32 and the main striking rod 26.
